Conventional root canal therapy cleans and fills the pulp chamber with biologically inert material after destruction of the pulp due to dental caries, congenital deformity or trauma. Signs of systemic involvement, 2. The presence of dens evaginatus or dens invaginatus were the second most common etiology of pulp necrosis in immature teeth. Mineralised tissue was found embedded in the newly formed tissue. Published four times a year—January, April, July, and October—each issue focuses on a single topic in dentistry and is presented under the direction of an experienced guest editor. Clinically, regenerative endodontic treatment is carried out in teeth with necrotic pulps and immature apices. Regenerative Endodontics and Tissue Engineering: What the Future Holds. Endodontics : Oral Therapeutics 1963 July Occlusal : Rehabilitation 1963 November Periodical Therapy 1964 March Genetically modified virus to maintain human DNA are vectors commonly used 14. Various types of scaffolds such as natural, or synthetic, polymers are being studied and reported with varying results . [2] This new treatment modality aims to promote normal function of the pulp. Chogle | Harold E. Goodis Sleep Medicine and Dentistry. Then, irrigation of the canal is carried out with  sodium hypochlorite solution and physiological saline, which is later dried and intracanal medicament (such as triple antibiotic paste) is placed into the canal. It is established that these procedures were actually stem cell-based procedures. Therefore, sodium hypochlorite is advised to be used at a lower concentration so as to achieve the optimum effect for antimicrobial activity and differentiation of the stem cells. Electronic address: paurazsb@udmercy.edu. Bacterimia ~ 324 ~ International Journal of Applied Dental Sciences Locally used antibiotic agents in endodontics (Table - 2) 1. Since January 2016, the journal has dedicated a section to regenerative endodontics with the aim of contributing to the rapid evolution of this field . First appointment focuses on disinfection of the pulp space. Septomixine Forte 8. Nonetheless, the presence of nerve endings suggests the presence of a vital tissue that is immune-competent due to the intimate association of innervation with blood vessels and the immune system.

Kinaia, Sami M.A. The concept of cell homing in dental pulp and dentin regeneration was first proposed in 2010. Matoug-Elwerfelli M(1), Duggal MS(2), Nazzal H(3), Esteves F(4), Raïf E(1). [43] Therefore, a focus on “revascularization” would disregard the potential role of growth factors and scaffolds in histological recapitulation of the pulp-dentin complex. Regenerative endodontic procedures (REPS)[1] is defined as biologically based procedures designed to replace damaged structures such as dentin, root structures, and cells of the pulp-dentin complex. [40][41][42] On the contrary, the concept of revascularization focuses only on the delivery of blood into the root canal space to allow the pulp space to be filled with vital tissue as a means of prompting wound healing. Aim: To investigate the feasibility of decellularizing the entire dental pulp using a mild treatment protocol to develop a decellularized biological extracellular matrix scaffold for use in regenerative endodontic procedures. [44] This indicates that a space that was previously vacant (debrided root canal) may become populated with an innervated tissue supported by vascularity. In both dens evaginatus and dens invaginatus, direct exposure of pulp to the oral environment will eventually lead to inflammation and infection of the pulp. [35][36] This is an essential principle in the interpretation of clinical regenerative studies. A biocompatible decellularized pulp scaffold for regenerative endodontics M. Matoug-Elwerfelli1, M. S. Duggal2, H. Nazzal3, ... scanning electron microscope and DNA quantification assay. Before this treatment modality is introduced, apexification procedures using either immediate placement of mineral trioxide aggregate (MTA)[3] apical plug or long term-calcium hydroxide treatment[4] were traditionally used to treat immature permanent tooth. Odontogenesis is a multiplex and long process of postnatal organogenesis. Based on this definition, regenerative Decellularized Human Dental Pulp as a Scaffold for Regenerative Endodontics Show all authors. Medicated Gutta Percha 9. Regenerative endodontics involves a two- or multi-step procedure. 2007). Long term calcium hydroxide treatment[4] or placement of mineral trioxide aggregate (MTA)[3] apical plug was performed. Both vital and non vital pulp therapies should be taken into consideration to keep the natural teeth as long as possible. Although angiogenesis and the establishment of a functional blood supply is a key feature in the maintenance and maturation of a regenerating tissue, positive responses to pulp sensitivity tests such as cold or EPT have been reported in some of the published cases. The presence of dens evaginatus[16] can lead to rapid pulpal necrosis when there is continuous trauma from occlusion. Chogle | Harold E. Goodis Sleep Medicine and Dentistry. A study showed that regenerative endodontic procedures had better clinical outcomes as compared to apexification procedures, both with MTA and calcium hydroxide such as in aspects of absence of pain, swelling and sinus tracts. This article is peer-reviewed and available for 2 hours of CE credit. Regenerative endodontic procedures depend on efficient and powerful  chemical disinfection, which is then followed by the repair and growth of the tooth that promotes continued root development and re-establishment of nerve functions of the tooth. Regenerative endodontics is an exciting new area of practice that uses biologically-based materials to stimulate natural healing processes in damaged teeth. Volume 56, Issue 3 July 2012. Chogle, Harold E. Goodis, Bassam Michael Kinaia, https://doi.org/10.1016/j.cden.2012.05.002, Bassam Michael Kinaia, Sami M.A. The incidence of dens evaginatus has been reported to affect up to 6% of the population, with greater incidence in certain ethnic groups. Medicament dressing was placed and intracanal bleeding was evoked. Thus, the primary therapeutic goal of regenerative endodontic procedures is to promote the healing, survival and function of the tooth. Dental Clinics of North America updates you on the latest trends in patient management and the newest advances, as well as provides a sound basis for choosing treatment options. King's College London published in January 2017 on the regeneration of dentine with collagen sponge filled with glycogen synthase kinase (GSK-3) 2012 Feb 18; doi: 10.1002/jbm.a.34064. . Regenerative endodontics has encountered substantial challenges toward clinical translation. Scaffold in Regenerative Endodontics Manal Matoug-Elwerfelli Submitted in accordance with the requirements for the degree of Doctor of Philosophy The University of Leeds School of Dentistry November 2017 .

Get access to a complete library of educational presentations and materials —as well as the ability to earn CE credit online — through Endo On Demand. All articles related to the field of regenerative endodontics until December 2017 were included. He hypothesized that the presence of blood clot within the root canal promotes healing of the pulp, hence maintaining the vitality of the pulp. Resolution of symptoms of inflammation related to enlargement of foramen and overinstrumentation were observed in as early as 17 days. Some other potential sources of postnatal stem cells in the oral environment are the tooth germ progenitor cells (TGPCs), dental follicle stem cells (DFSCs), salivary gland stem cells (SGSCs), stem cells from human exfoliated deciduous teeth (SHED), periodontal ligament stem cells (BMSCs), oral epithelial stem cells (OESCs), gingival-derived mesenchymal stem cells (GMSCs) and periosteal stem cells (PSCs). Regenerative endodontics has been defined as "biologically based procedure designed to replace damaged structures, including dentin and root structures, as well as cells of the pulp-dentin complex." To replace live tissue, either the existing cells of the body are stimulated to regrow the tissue native to the area or bioactive substances inserted in the pulp chamber. [45][46], The secondary therapeutic goal of regenerative endodontic procedures is continued root development. It is seen on clinical and radiographic examination as an additional cusp, typically projecting into the occlusal table of a mandibular premolar. Disinfecting agents for regenerative procedures include sodium hypochlorite, antibiotic or calcium hydroxide dressings. Cytotoxicity assays to determine decellularized scaffold biocompatibility were also performed. The contribution of the … The goal of regenerative endodontics is to reinstate normal pulp function in necrotic and infected teeth that would result in reestablishment of protective functions, including innate pulp immunity, pulp repair through mineralization, and pulp sensibility. Regenerative protocols and immature teeth. These literatures provided the fundamental knowledge of factors essential for revascularization to occur, notably the evidence that teeth with immature roots and open apices had elevated rates of revascularization and continued root development.
